Specification of Letters Patent.

Application filed December 21, 1916. Serial No. 138,253.

T 0 all whom it may concern:

Be it known that 1, JOHN M. BAILEY, residing at Hillsboro, in the county of Montgomery and State of Illinois, have invented a new and Improved Pinch-Bar, of which the following is a specification.

My invention which has reference to im-- provements in pinch bars or like lever appliances, primarily has for its purpose to provide an improved pinch bar of a simple, inexpensive and compact construction, and in which the cooperative parts are especially designed for effecting a duplex pinch or leverage action on the wheel or other object to be started under each operative movement of the lever or bar member, whereby the lever when operatively applied, as it is forced down, first operates to impart an initial rotation to the wheel and, as it finishes the down or forced movement, it efiects a final and more powerfulpinching action on the wheel that simultaneously imparts a turning and a forwardly sliding motion to the said wheel.

With other objects in inafter' be referred to, my invention is an improved implement of the general character stated that embodies the peculiar features of construction and novel combination of the parts presently fully explained, spe-- cifically pointed out in the appended claims and illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of a pinch bar constructed in accordance with my invention, the bar being operatively positioned for effecting the initial pinching action on the wheel.

2 is a similar view of my improved pinch bar, the lever or bar being shown at its final or down position for eiiecting a more powerful leverage or pinching contact with the wheel.

Fig. 3 is a top pinch bar.

Fig. 4. thereof.

Fig. 5 is a longitudinal section of the same taken substantially on the line 5-5 of Fi 6.

Fig. 6 is a cross section of the same on the line 66 of Fig. 5.

Fig. 7 is a perspective view of the supplemental pinching member, and

Fig. 8 is a view that will hereperspective view of the is an inverted perspective view similar view of the main pinching member hereinafter specifically referred to. p In carrying out my invention, the metal body of my improved pinch bar consists of a main portion 1 and a supplemental member 12 and the said main portion 1 also includes a beveled pinching jaw 22 adapted for being slid between the bottom of the wheel tread and the raiL'as is indicated in Figs. 1 and 2, when operatively applying the same, and the said portion 1 further includes lateral members 3-3 that project below the underside 11 of the said portion 1. The said members 3 are each bifurcated to form ears 30-30 for pivotally receiving a pair of oppositely disposed rail claws or grippers 1 i, each of which is inthe nature of an angled member, the portion lO-of which forms the clamp for tting over the outer edg'e of the rail, while the other portion 11 forms a bearing for seating on top of the rail, as shown, and for normally claws or grippers themain portion or casting 1 is formed with a. transverse socket 4* for receiving therein a bow spring 6 with which the bearing portions ll-l1 of the claws engage and by spreading the opposing. l--l-, theunder face of Patenteolflct. 2a, .1917.

which the said claws are normally held spread apart to provide for quickly applying the pinch bar along the rail and for releasing the claws from the said rail when the leverage power on the body portion 1 is released.

The body portion 1 of the appliance includes a bifurcated rear end 7 which merges with the longitudinal seat 8 in the upper front face of said body, as is best shown in Fig. 3, by reference to which it will be seen that the supplemental member 12 includes a body portion 13 that rockably fits between the bifurcated rear end 7 of the member 1 to which it is secured by a pivot pin 14:.

The body 13 is formed with a forwardly projected extension the seat 8 in the member 1 when the parts are assembled for being operatively applied, as is shown in Fig. 1, andthe rear end of the said body 13 has a socket 16 for receiving the lower end of the operating lever or handle 17 The body 13,. where it passes beyond the bifurcated end of the portion or body 1, is thickened laterally and the opposite side faces are cut out to provide side lugs 18 which are provided to cooperate with lugs i of sharp edges for 99 on the body 1, the reason for which will presently appear.

l9 esignates a pinch member rockably mounted in the outer bifurcated end of the extension 15 of the supplemental pinch bar or body 12 and the said member 19 has its face concaved to thereby produce a pair causing the said pinch member 19 to positively, bight the face of the car wheels, when it is applied as shown in Fig. 1.

From the foregoing description taken in connection with the accompanying drawing, it is believed that the complete construction and manner of operation and the advantages of my invention will be readily apparent.

In using my improved pinch bar, the body portion 1 is applied to the top of the rail with the clamping jaw straddling the same and the lower end of the main and supplemental pinch or lifting members are placed under the car wheel, as is clearly shown in Fig. 1 and, when thus positioned, as the lever is forced down, see the arrow as, the supplemental portion will first swing up with its rockable member 19 against the under side of the wheel tread face, it being understood that as the pressure is applied to the pinch bar lever, the clamping jaws 4 are caused to close in and firmly grip the rail, the greater the pull force on the lever, the greater rail gripping action of the pivoted claims or jaws 4-.

As the pinch member 12 lifts the wheel, it also tends to shove the wheel forwardly until the side lugs 18-18 thereon engage the stop lugs 9-9 on the main or body portion 1 and, when this occurs, the initial pinching operation ceases, since the other down pull 011 the lever, by reason of the two parts 1 and 12 now moving as one, the front or pinch jaw end of the body 1 now engages the wheel and tends to turn and crowd it forwardly, see the arrow y on Fig. l. The operation of sliding the bar along the rail is simple, since when pressure on the lever is released, the spring 6 engaging the clamp jaws, loosens the grip of the said jaws from the rail.

What I claim is:

1. A pinch bar consisting of a main I and'terminate in bifurcated body portion being naaaeie member having a beveled pinching jaw at the outer end, a bifurcated rear end, a longitudinal seat in the upper face of the solid front portion and lateral members that project below the under face of the solid body pendent apertured ears, and a supplemental member having a handle receiving socket, a forwardly projecting extension that closes down into the longitudinal seat in the main member when the parts are assembled, means pivotally connecting main member, said supplemental and main members having interengaging lugs for causing the twomembers to move as one when the bar is operatively applied, rail gripper claws pivotally mounted in the pendent apertured ears on the main memmember rockably mounted her and a pinch in the outer end of the supplemental member.

2. In a pinch bar, the combination with a'body portion having a beveled pinch jaw at the outer end, integral lateral members each terminating in a pair of pendent apertured ears, the rear part of the said longitudinally bifurcated, the upper face of the solidportion of the said body having a longitudinal seat and the under face thereof a transverse socket in line with the pendent apertured ears, the rear end of the said body portion having stop lugs; of a supplemental mem-v ber that includes a body portion, means for pivotally mounting the said body portion in the bifurcated rear endof the main portion, the said body portion of the supplemental member including a forwardly pro jecting extension adapted for fitting in the longitudinal seat in the main body portion, a handle receiving socket, and lateral lugs for engaging the lugs on the main body portion, a pinch member rockably mounted in the front end of the supplemental mem her, angle shaped rail gripping claws pivot-ally mounted in the opposite pair of apertured ears on the main body portion, and a spring seated in the recess on the main body portion tending to normally spread the said rail gripping claws.
